Aloinjertos análogos de mucosa bucal en ratas no consanguíneas

Abstract

Introducción. A pesar de que existen opciones terapéuticas para el tratamiento de defectos de la mucosa bucal, persiste la necesidad de encontrar sustitutos funcionales, anatómicos y estéticamente similares al tejido que se va a reemplazar, así como soluciones que reduzcan la morbilidad de los injertos autólogos. Objetivo. Determinar la compatibilidad clínica e histológica de aloinjertos equivalentes de mucosa bucal elaborados mediante ingeniería tisular en ratas no consanguíneas. Materiales y métodos. Se utilizó una muestra de mucosa bucal de ratas Sprague Dawley para la obtención de un cultivo de fibroblastos y otro de queratinocitos y fibroblastos. En ambos casos, se usó una membrana de colágeno comercial como soporte. Después de diez semanas de cultivo, las membranas resultantes se injertaron en cuatro ratas Wistar. La primera fase del estudio consistió en la elaboración de los tejidos análogos de mucosa bucal mediante ingeniería tisular, los cuales se implantaron en ratas Wistar inmunocompetentes; posteriormente, se evaluaron las características clínicas e histológicas del aloinjerto. Resultados. La evaluación in vivo de los tejidos análogos demostró que se habían integrado correctamente en los huéspedes inmunocompetentes, y se había logrado el aumento del biotipo periodontal y la creación de una zona con mayor queratinización. Desde el punto de vista histológico, el tejido adquirió características similares a las de la muestra de mucosa bucal de control, sin ningún tipo de reacción inflamatoria ni signos clínicos o histológicos de rechazo. Conclusión. Hubo compatibilidad clínica e histológica de los aloinjertos equivalentes de mucosa bucal obtenidos mediante ingeniería tisular.
